For the 2250 I think you will need seven of the bulbs. (Maybe 8)
Many TV audio shops have the 200ma fuse bulbs. I would be that there are some some TV repair shops that will have them as well. If not, you can always go to ePay and enter "Marantz Bulb" in the search que. You will definitely come up with the bulbs you need there. The originals were 200ma 8v Fuse Bulbs. I have heard of people putting in 250ma etc.
I started a thread a couple of days ago asking what the best method is to replace them. (apearrantly it is to go through the front, instead of the back (as I had tried doing:thumbsdn: )).
There is a man here who sells an LED version of the fuse bulb. Based upon the photos, it will give your machine a DEEP blue color instead of the turquoise blue that the incandescent 200ma's produce. The run cooler, and do not suck up as much energy as the incandescents do. If you like the original
turquoise, go with the incandescent, if you want a DEEP
BLUE color, go for the LED's. Apearantly they last longer as well. I have yet to try it out...
Best of luck to you.
